Who cares about real-world results in this business? I just had to prepare a huge set of apks for a hardware demonstration on beta hardware my office hasn't even SEEN. We were given basic specs (screen, cpu....that's pretty much it), and told to deal with it.

The problem is that the "real world" as we know it won't be here tomorrow. By this time next week, the hardware landscape will have changed 5 times. Every day the specs for another "ultimate" smartphone get leaked, and every day another one is released to minimal fanfare. Doing projects on a specs-only basis is becoming commonplace. : (
